The GA-2100BM-7A2ER is a slim, octagonal-cased G-Shock in a white resin finish, part of Casio's 'CasiOak' line. It runs on quartz with analog hands plus a small digital display, and packs a stopwatch, countdown timer, alarms and a full calendar. At 200m water resistance and roughly 45mm across but only about 11mm thick, it wears lighter and flatter than most G-Shocks. It suits people who want a tough everyday watch with a streetwear look; rivals like the GA-2100 base models offer the same movement and toughness, while metal-cased versions add weight and cost.

Owners of the GA-2100 family praise the slim octagonal case and the toughness for the size. Many like the analog-digital mix and the light weight. Common complaints are legibility of the small digital window and the resin picking up marks over time.
